FIG. 4 is a diagram illustrating a sectional view of an interior of a touch screen, according to an embodiment of the present invention.

Referring to FIG. 4, the touch screen 190 is configured such that a first touch panel 190 a for detecting a touch input of a finger or the input unit 167, a display panel 190 b for displaying a screen, and a second touch panel 191 for detecting an input of the input unit 167, are sequentially stacked. According to an embodiment of the present invention, the first touch panel 190 a of the touch screen 190 may be located below the display panel 190 b.

The first touch panel 190 a is a capacitive touch panel, and is obtained by coating a thin metallic conductive material (for example, an Indium Tin Oxide (ITO) film) on opposite surfaces of glass, such that a current flows along surfaces of the glass, and coated with a dielectric material capable of storing electric charges. When a finger of the user or the input unit 167 touches a surface of the first touch panel 190 a, a predetermined amount of electric charges are moved by static electricity, and the first touch panel 190 a recognizes a change in a current due to movement of electric charges to detect a touch location.

The display panel 190 b includes a plurality of pixels, and displays an image through the pixels. For example, the display panel 190 b may be embodied as an LCD), an Organic Light Emitting Diode (OLED), or an LED.

The second touch panel 191 is an Electronic Magnetic Resonance (EMR) type touch panel, and includes an electronic inductive coil sensor having a grid structure, such that a plurality of loop coils are disposed in a first direction and a second direction crossing the first direction, and includes an electronic signal processing part for sequentially providing an AC signal having a predetermined frequency to the loop coils of the electronic inductive coil sensor. When the input unit 167, having a resonance circuit therein, is located adjacent to a loop coil of the second touch panel 191, the electric field generated from the loop coil generates a current based on electromagnetic induction in a resonance circuit of the input unit 167. An inductive magnetic field is generated in a coil 530 constituting a resonance circuit in the input unit 167, and the second touch panel 191 detects an inductive magnetic field from the loop coil in a signal receiving state to detect a hovering location and a touch location of the input unit 167. The portable terminal 100 may detect a hovering height h, between the display panel 100 to a pen tip 541 of the input unit 167.

It will be understood by those skilled in the art that the hovering height h can be changed to correspond to a performance or structure of the portable terminal 100.

The second touch panel 191 may be dedicatedly used for detection of hovering or a touch by the input unit 167. The input unit 167 may be referred to as an electromagnetic pen or an EMR pen. The input unit 167 may be different from a general pen which does not have a resonance circuit detected by the first touch panel 190 a. The input unit 167 may include a button 542 for changing an electromagnetic induction value generated by the coil 530 located in an area adjacent to the pen tip 541. The input unit 167 is described in greater detail below with reference to FIG. 5.

The touch screen controller 195 may include a first touch panel controller corresponding to the first touch panel 190 a, and a second touch panel controller corresponding to the second touch panel 191. The first touch panel controller converts an analog signal received by detection of a touch of a finger or the input unit 167 from the first touch panel 190 a into a digital signal (for example, X and Y coordinates) to transmit the digital signal to the controller. The second touch panel controller (not shown) converts an analog signal received by detection of hovering or a touch of the input unit 167 from the second touch panel 191 into a digital signal (for example, X, Y, and Z coordinates) to transmit the digital signal to the controller.

The controller 110 may control the first touch panel 190 a, the display panel 190 b, and the second touch panel 191 by using the digital signals received from the first touch panel controller and the second touch panel controller. The controller 110 may display a screen on the display panel 190 b in response to a touch or hovering of a finger or the input unit 167. One touch screen controller 195 may control the first touch panel 190 a and the second touch panel 191.

The pen communication unit 520 may receive a control signal transmitted from the portable apparatus 100 and transfer the control signal to the pen controller 510. The pen communication unit 520 may analyze a control signal received from the portable apparatus 100. Although Bluetooth communication is used as an example of a short-range communication unit in an embodiment of the present invention, it may be replaced by or used together with a short-range communication unit, such as, for example, Zigbee, an Ultra Wide Band (UWB) communication, or an RFID, by which a communication channel can be formed in a short range and a signal can be transmitted and received.

The coil 530 generates an inductive magnetic field through an interaction with a loop coil of the second touch panel 191 of the portable apparatus 100. The portable apparatus 100 may receive an inductive magnetic field generated by the coil 530 and detect a hovering location and a touch location of the input unit 167. The portable terminal 100 may detect a height h from the touch screen 190 to the pen felt-tip 541 of the input unit 167.

When the pen button 542 is pressed by the user, it may change an electromagnetic induction value generated in the coil 530. The pen button 542 may include a physical button or a touch button.

The pen speaker 543 may output various sound sources stored in the pen memory 550 under the control of the controller 510. The pen speaker 543, according to an embodiment of the present invention, may output auditory feedback corresponding to a first control command received from the portable apparatus 100 in response to a copy command generated by the button 542. The pen speaker 543 may output auditory feedback corresponding to a second control command received from the portable apparatus 100 in response to a paste command generated by the button 542. The pen speaker 543 may output a sound corresponding to a vibration period and/or a vibration intensity of the pen vibration element 520. The pen speaker 560 may output a sound corresponding to first and/or second control signals output to the input unit 167 substantially together with the speaker 163 included in the portable apparatus 100 (for example, a time interval of 5 ms or less) or after a predetermined time period (for example, 20 ms).

The pen vibrating element 544 may convert an electrical signal into mechanical vibrations under the control of the pen controller 510.

According to an embodiment of the present invention, the pen vibrating element 544 may be activated based on a first control signal and/or a second control signal received from the portable apparatus 100, and may provide haptic feedback to the user. The pen vibrating element 544 may vibrate the entire input unit 167 or a portion of the input unit 167.

The pen memory 550 may store a signal or data that is input or output to correspond to operations of the pen communication unit 520, the coil 530, the pen button 542, the pen speaker 543, the pen vibrating element 544, and the pen battery 560, under the control of the pen controller 510.

For example, the input information may include a model name, a unique unit ID, a residual size of a memory, existence of object data, a Bluetooth version, or a Bluetooth profile. The pen memory 550 may store one or a plurality of haptic waveforms in which the pen vibrating element 544 vibrates based on first and/or second signals received from the portable apparatus 100.

The pen battery 560 may supply electric power to the elements 510 to 550 of the input unit under the control of the pen controller 510. When the battery level is not sufficient, the pen battery 560 may be recharged wirelessly or through a separate wired cable.

According to an embodiment of the present invention, a control signal is received through the pen communication unit 520 of the input unit 167 under the control of the pen controller 510. The control signal is a signal received from the portable apparatus 100, and may be periodically received by the input unit 167 for a predetermined time period or until a time point when hovering is completed. For example, the control signal includes information for activating a mode of a vibrating element 544 of the input unit 167, information for representing a vibration intensity of the input unit 167, information for deactivating a mode of the vibrating element 544 of the input unit 167, and information for representing a total time for which the pen vibrating element 544 vibrates. The control signal has a size of about 8 bytes, and may be repeatedly transmitted by the portable apparatus 100 according to a predetermined period (for example, 5 ms). For example, the control signal may include information in Table 1.

An example of an application screen displayed on the touch screen 190 will be easily understood by those skilled in the art.

The controller 110 may discover the input unit 167, which can perform a Bluetooth communication, by using a communication unit. The controller 110 may receive device information (for example, a model name, a unique unit ID, a residual size of a memory, a Bluetooth version, or a Bluetooth profile) from the input unit 167 through a communication unit. When being connected to the input unit 167, the controller 110 may perform pairing with the input unit 167 through a communication unit. The controller 110 may perform pairing with the input unit 167 manually (for example, discover the input unit 167 from the portable apparatus 100) or automatically (for example, display a pop-up for registration of an input unit 167 when the input unit 167 is detected from the portable apparatus 100). The controller 110 may receive device information (for example, a model name, a unique unit ID, a residual size of a memory, a Bluetooth version, or a Bluetooth profile) of the input unit 167 through pairing. The controller may receive device information of the input unit 167 after pairing. The received device information is stored in the storage unit of the portable apparatus 100. The controller 110 may perform various embodiments of the present invention by using the device information of the input unit 167. The portable apparatus 100 and the input unit 167 may communicate with a counterpart device through pairing, and share a link key, which is to be used in a verification process, to set a mutually encrypted connection, which means that data can be transmitted mutually.

An example of the device information of the input unit 167 will be easily understood by those skilled in the art.

In step S602 of FIG. 6, a first touch of an input unit is detected.

Referring to FIG. 7B, the object 711 displayed on the application screen 710 is touched by the input unit 167. The controller 110 may detect a first touch 712 of the input unit 167 from the application screen 710 through the touch screen 190, the pen recognition panel 191, and the touch screen controller 195. The controller 110 may receive first location information (for example, X1 and Y1 coordinates) corresponding to the first touch 712 from the touch screen controller.

The controller 110 may detect hovering 712 a of the input unit 167 from the application screen 710 through the pen recognition panel 191 and the touch screen controller 195. The controller 110 may receive second location information (for example, X2 and Y2 coordinates) corresponding to hovering 712 a detected from the touch screen controller.

The controller 110 may store a touch on the touch screen 190 included in the received first location information, a hovering location on the touch screen 190 included in the second location information, a touch detection time, and touch information (for example, a touch pressure or a hovering height) corresponding to the touch in the storage.

It will be easily understood by those skilled in the art that the number of detected touches may be changed to correspond to a performance or structure of the portable apparatus 100.

In step S603 of FIG. 6, an object to be copied is selected.

Referring to FIG. 7C, the controller 110 may select the object 711 corresponding to the touch 712 of the input unit 167. The controller may select the object 711 corresponding to hovering 712 a of the input unit 167. For example, the object 711 may be selected by displaying a periphery 711 a of the object 711, displaying a separate symbol (for example, □, ⋄, and ∘) at the periphery 711 a of the object 711, or displaying the object 711 in different colors. The controller 110 may select the object 711 by using first location information (X1 and Y1 coordinates) corresponding to the touch 712 of the input unit 167 received from the touch screen controller 195 or second location information (X2 and Y2 coordinates) corresponding to hovering 712 a. The controller 110 maps object information (for example, a file name, a file size, a file type, a file extension, or a file storage location) corresponding to the selected object 711 with device information of the input unit 167 stored in advance, to store the mapping result in a temporary storage space in the application 710 or a clip board. The controller 110 may provide at least one of visual feedback (for example, a flash and a video) through the touch screen 190, auditory feedback (for example, output of a sound) using the speaker 163, and haptic feedback (for example, output of vibrations) using the vibration motor 164 to correspond to selection of the object 711.

The controller 110 may perform a control to transmit a first control signal corresponding to haptic feedback (for example, output of vibrations) to be output from the pen vibrating element 544 through a communication unit, in response to device information of the input unit 167 and selection of the object 711, to the input unit 167 in a Bluetooth Serial Port Profile (SSP). The input unit 167 may output haptic feedback (for example, output of vibrations) from the pen vibrating element 544 based on a first control signal received from the portable apparatus 100.

The controller 110 may perform a control to transmit a first control signal corresponding to auditory feedback (for example, output of a sound) to be output from the pen speaker 543, in response to device information of the input unit 167 stored in advance and selection of the object 711, to the input unit 167 in a Bluetooth Serial Port Profile (SSP), separately from the first control signal corresponding to haptic feedback, through a communication unit. The input unit 167 may output auditory feedback (for example, output of a sound) from the pen speaker 543 based on the first control signal received from the portable apparatus 100. The pen controller 510 may provide one of haptic feedback and auditory feedback, or a combination of haptic feedback and auditory feedback.

The controller 110 may perform a control to transmit one of a first control signal, where haptic, auditory, or visual feedback provided by the portable apparatus 100 is the same as haptic, auditory, or visual feedback provided by the input unit 167, and another control signal through a communication unit.

In step S604 of FIG. 6, it is determined whether a copy command, input via a button of the input unit, is received.

Referring to FIG. 7D, the controller 110 may receive a copy command for the selected object 711 from the input unit 167 in a Bluetooth Serial Port Profile (SPP). The controller maps the received copy command with the device information of the input unit 167 stored in advance and stores the mapping result in the storage.

When the button 542 is pressed 713 by the user, the pen controller 510 may convert an operation mode of the input unit 167 into a copy mode. If an input of touching the button 542 is generated by the user when the button 542 is of a touch type, the pen controller 510 may convert an operation mode of the input unit 167 into a copy mode. The pen controller 510 may perform a control to transmit a copy command to the portable apparatus 100 through the pen communication unit 520. The copy command may be transmitted periodically (for example, every 50 ms) for a predetermined time period (for example, 5 s) through the pen communication unit 520 under the control of the pen controller 510. The predetermined time may be variably regulated. When the button 542 is pressed once more by the user, the pen controller 510 may release the copy mode, which is a current operation mode of the input unit 167. When the button 542 of the input unit 167 that is hovering is pressed 713 by the user, the pen controller 510 may convert an operation mode of the input unit 167 into a copy mode. The pen controller 510 may perform a control to transmit a copy command to the portable apparatus 100 through the pen communication unit 520 in the Bluetooth Serial Port Profile (SPP). The copy command may be transmitted periodically (for example, every 50 ms) for a predetermined time (for example, 5 s) through the pen communication unit 520 under the control of the pen controller 510. When the button 542 is pressed 713 once more by the user, the pen controller 510 may release the copy mode, which is a current operation mode of the input unit 167.

When a copy command, input via a button of the input unit 167, is received, a visual feedback is displayed on the touch screen and a control command corresponding to haptic feedback is transmitted to the input unit 167, in step S605 of FIG. 6.

Referring to FIGS. 7E and 7G, the controller 110 may perform a control to display visual feedback 714 by which the object 711 is reduced from a current size (for example, 200 pixels×240 pixels) to a predetermined size 711 b (for example, 50 pixels×50 pixels, which is 25% of the original size) in response to the received copy command. The visual feedback 714 is gradually reduces the current size of the object 711 to the predetermined size 711 b. The visual feedback 714 may reduce the object 711 to a predetermined size 711 b with reference to a central location of the current size of the object 711. When the visual feedback 714 completely reduces the object 711 to the predetermined size 711 b and the input unit 167 becomes more distant from the touch screen 190 than a height where hovering of the input unit 167 is detected, the controller may not display the reduced object 711 b. When the input unit 167 is closer to the touch screen 190 than a height where hovering of the input unit is detected, the controller may display the reduced object 711 b.

The controller 110 may perform a control to transmit a first control signal to the input unit 167 in a Bluetooth Serial Port Profile (SPP) by using device information of the input unit 167 stored in advance, in response to the received copy command. The first control signal may include haptic information on haptic feedback 715 to be output through the pen vibrating element 544. For example, Table 1 is an example of haptic information. The first control signal may include auditory information on auditory feedback 716 to be output through the pen speaker 543. The auditory information may include a sound source to be output through the pen speaker 543. The input unit 167 may store haptic information corresponding to the haptic feedback and auditory information corresponding to the auditory feedback in the pen memory 550 in advance. The control information may include a file name, a file type, the pen speaker 543 activation information, sound intensity information, and the pen speaker 543 deactivation information corresponding to a sound source stored in the pen memory 550.

The controller may simultaneously perform transmission of a first control signal to the input unit 167 and displaying of visual feedback, or may perform one of transmission of the first control signal and displaying of the visual feedback first.

According to an embodiment of the present invention, additional visual feedback 714 a using a new object 714 b, as well as visual feedback of the object 711, may be selectively provided. Referring to FIG. 7F, when the visual feedback 714 is displayed, the new object 714 b is displayed adjacent to (for example, 20 mm or less) the object 711. The new object 714 b is an empty pipette that has not suctioned a liquid. The controller may display the pipette 714 b, which gradually suctions a liquid in response to the visual feedback 714 by which the size of the object 711 is gradually reduced to a predetermined size. When the object 711 is completely reduced to a predetermined size 711 b, the controller 110 may display a pipette 714 c that has completely suctioned a liquid. The controller 110 may display the pipette 714 c that has completely suctioned a liquid for a predetermined time period (for example, 500 ms).

The controller 110 may perform a control to output haptic feedback through the vibration motor 164 as well as through visual feedback in response to the received copy command. The controller 110 may vibrate the vibration motor 164 to correspond to haptic information as shown in FIG. 8 to provide haptic feedback. FIG. 8 is described in greater detail below with respect to step S606 of FIG. 6. The controller 110 may perform a control to output a sound source corresponding to auditory feedback through the speaker 163, as well as visual feedback, in response to the received copy command.

In step S606 of FIG. 6, the input unit 167 provides haptic feedback and auditory feedback.

Referring to FIGS. 7E and 8, the pen controller 510 may receive a control command in a Bluetooth Serial Port Profile (SPP) through the pen communication unit 520. The pen controller 510 may control such that the pen vibrating element 544 outputs (for example, FIG. 8) haptic feedback, corresponding to haptic information included in control information, in response to the received control command.

The transverse axis (X axis) of FIG. 8 represents a vibration time period of the pen vibrating element 544, in units of 50 ms 805 a. The longitudinal axis (Y axis) represents a vibration intensity of the pen vibrating element 544, in units of 500 mV 805 b. As shown, the haptic waveform corresponding to the haptic information of FIG. 8 gradually increases from 0 V to 1.6 V and rapidly decreases to 0V in the vibration.

In a preprocessing section 810 a, the pen controller 510 may analyze and/or store control information received by the portable apparatus 100 and supply electric power to the pen vibrating element 544. For example, the preprocessing section 810 a may refer to a section before vibrations are generated in the pen vibrating element 544.

An acceleration section 810 b is a section in which a vibration time period and a vibration intensity of the pen vibrating element 544 increase. A maximum intensity 810 d of the acceleration section 810 b may be changed according to a file size and a copy processing time period included in the copy information. For example, the maximum acceleration section and the maximum intensity of the acceleration section whose file size is 1 MB may be greater than those of the acceleration section whose file size is 500 KB. The copy processing time period and the maximum intensity of the acceleration section whose copy processing time period is 1.5 s may be greater than those of the acceleration section whose copy processing time period is 500 ms.

A deceleration section 810 c is a section in which vibrations of the pen vibrating element 544 corresponding to the maximum intensity 810 d decelerate. The pen controller 510 may complete the output of haptic feedback in the deceleration section 810 c. The time axis of the deceleration section 810 c may be shorter than or equal to the time axis (X axis) of the acceleration section 810 b. In an embodiment of the present invention, various haptic waveforms (for example, FIGS. 13 to 15), whose vibration time periods, vibration periods, and vibration intensities are different, may be stored in addition to FIG. 8, and another haptic waveform may be generated and stored by using a combination of the haptic waveforms (for example, FIGS. 13 to 15) that are stored in advance.

The pen controller 510 may perform a control to output auditory feedback corresponding to auditory information (for example, a sound source) included in control information from the pen speaker 543 in response to the received control command. The pen controller 510 may perform a control to selectively output one of haptic feedback and auditory feedback.

In step S607 of FIG. 6, it is determined whether a residual size of the memory of the input unit 167 is sufficient.

The controller may compare a residual size of the pen memory 550 of the input unit 167 with a file size included in object information of the object 711, by using device information of the input unit 167 stored in advance.

According to the comparison result, the controller may transmit one of copy information including object data of the object 711 and copy information excluding object data of the object 711 to the input unit 167.

In an embodiment of the present invention, it will be easily understood by those skilled in the art that the residual size of the memory of the input unit may be identified in steps S603 to S605.

When the residual size of the memory of the input unit 167 is not sufficient, copy information is transmitted to the input and the external server, in step S612.

When the residual size of the pen memory 550 is smaller than a file size of the object 711, the controller may perform a control to transmit first copy information without object data of the copy information corresponding to the object 711 to the pen communication unit 520 by using device information of the input unit 167. The controller 110 may perform a control to transmit object data of the copy information to an external server through a URL of an external server of a manufacturer stored in the storage and a communication unit. The controller 110 may map the first copy information with the URL of the external server to store the mapping result. The controller 110 may receive object data transmitted to an external server by using the first copy information transmitted to the input unit 167. The controller 110 may store object data of the copy information in a clip board of the storage. The object data stored in the clip board may be pasted in the portable apparatus 100 by using the first copy information transmitted to the input unit 167.

It will be easily understood by those skilled in the art that in an embodiment of the present invention, a copy command, control information, and copy information are transmitted and received between the portable apparatus 100, the input unit 167, and the external server by using communication units of the portable apparatus 100, the input unit 167, and the external server which support various communication methods and the transmission/reception method is not limited to Bluetooth.

When copy information is completely transmitted to the external server (not shown), the controller may complete outputting of visual, haptic, and auditory feedbacks provided by the portable apparatus 100.

When the residual size of the memory of the input unit 167 is sufficient, copy information is transmitted to the input unit, in step S608.

When the residual size of the pen memory 550 is larger than a file size of the object 711, the controller may perform a control to transmit copy information corresponding to the object 711 to the pen communication unit 520 in a Bluetooth Serial Port Profile (SPP) by using device information of the input unit 167. The copy information may include object data, a file name, a file size, a file type, a file storage location, and a copy time period.

When copy information is completely transmitted to the input unit 167, the controller may output visual, haptic, and auditory feedbacks provided by the portable apparatus 100.

Returning to step S604 of FIG. 6, when a copy command is not input via a button of the input unit 167, it is determined whether a touch gesture of the input unit is detected, in step S609.

When a touch gesture (for example, a rotation, a flick, or a long press) by the input unit 167 is detected from the touch screen 190, the controller may detect a continuous movement (for example, continuous X and Y coordinates corresponding to a movement of the touch gesture) of the touch 712 by using the touch screen 190 and the touch screen controller 195. The controller may store a continuous movement starting from the detected touch 712 in the storage. The continuous movement of the touch 712 means that a contact on the touch screen is continued. For example, a long press may refer not to a continuous movement of a touch but to a touch gesture whose touch maintenance time period is 2 s or more.

When a touch gesture (for example, a rotation, a flick, or a long press) of the input unit 167 which is hovering is input to the touch screen 190, the controller may detect a continuous movement (for example, continuous X and Y coordinates corresponding to a movement of the touch gesture) of the input unit 167 by using the pen recognition panel 191 and the touch screen controller. The controller may store a continuous movement starting from the detected hovering location in the storage.

It will be easily understood by those skilled in the art that a touch gesture may be changed through setting of an environment in step S609 of FIG. 6.

When a touch gesture of the input unit 167 is not detected in step S609 of FIG. 6, the methodology terminates.

When a touch gesture of the input unit 167 is detected, a copy icon is displayed, in step S610.

Referring to FIG. 7H, the controller may display an icon group 720 in response to an input touch gesture. The icon group 720 includes a copy icon 720 a, a cut icon 720 b, and a delete icon 720 c. It will be easily understood by those skilled in the art that the icon displayed in the icon group 720 may be added, changed, or deleted to correspond to a performance or structure of the portable apparatus 100.

In step S611 of FIG. 6, a copy command is received by selection of a copy icon.

Referring to FIG. 7I, the copy icon 720 a is selected 721 from the displayed icon group 720 by the input unit 167. The controller receives a copy command corresponding to the selection 721 of the copy icon 720 a by the input unit 167. The controller maps the received copy command with device information of the input unit 167 stored in advance to store the mapping result in the storage. When the copy icon 720 a is selected, the controller may perform a control to remove the icon group 720.

The controller may perform a control to transmit a mode conversion signal of the input unit corresponding to the input copy command to the input unit. The pen controller 510 converts an operation mode of the input unit 167 into a copy mode in response to the received mode conversion signal. When the button 542 is pressed by the user, the pen controller 510 may release a copy mode, which is an operation mode of the input unit 167.

When the copy icon 720 a is selected by the input unit 167 that is hovering, the controller may perform a control to transmit a mode conversion signal of the input unit corresponding to the input copy command to the input unit. The pen controller 510 converts an operation mode of the input unit 167 into a copy mode in response to the received mode conversion signal. When the button 542 is pressed by the user, the pen controller 510 may release a copy mode, which is an operation mode of the input unit 167.

When a copy command is received via selection of the copy icon 720 a, the continues at step S605.

FIG. 9 is a flowchart illustrating a feedback providing method of a portable apparatus, according to an embodiment of the present invention.

FIGS. 10A to 10G illustrate feedback providing methods of a portable apparatus, according to various embodiments of the present invention.

FIG. 11 shows an example of haptic waveforms of a portable apparatus, according to an embodiment of the present invention.

In step S901 of FIG. 9, a second touch of the input unit 167 is detected.

Referring to FIG. 10A, the note application screen 720 is touched by the input unit 167. The controller 110 may detect a second touch 1012 of the input unit 167 from the note application screen 720 through the touch screen 190, the pen recognition panel 191, and the touch screen controller 195. The controller 110 may receive third location information (for example, X3 and Y3 coordinates) corresponding to the second touch 1012 from the touch screen controller 195.

Hovering 1012 a of the input unit 167 is detected in the note application screen 720. The controller may detect hovering 1012 a of the input unit 167 from the note application screen 720 through the pen recognition panel 191 and the touch screen controller. The controller may receive fourth location information (for example, X4 and Y4 coordinates) corresponding to hovering 1012 a detected from the touch screen controller.

The controller may store touch information (for example, a touch pressure or a hovering height) corresponding to a touch on the touch screen 190 included in the received third location information or a hovering touch, a touch detection time, and a touch on the touch screen 190 included in the fourth location information in the storage. The touch 1012 contacting the touch screen 190 may be generated, for example, by one of fingers or the input unit 167.

It will be easily understood by those skilled in the art that the number of detected touches may be changed to correspond to a performance or structure of the portable apparatus 100.

The controller 110 may receive device information (for example, a model name, a unique unit ID, a residual size of a memory, a Bluetooth version, or a Bluetooth profile) from the input unit 167. The controller 110 may receive copy information (for example, object data, a file name, a file size, a file type, a file storage location, and a copy time period) from the input unit 167. When copy information exists in the input unit 167, the controller 110 may receive copy information from the input unit. The received device information and copy information may be stored in the storage. The controller 110 may perform various examples of the present invention by using the device information of the input unit 167.

In step S902 of FIG. 9, a paste location is selected.

Referring to FIG. 10A, the controller 110 may select a paste location corresponding to the touch 1012 of the input unit 167. The controller 110 may select a paste location corresponding to hovering 1012 a of the input unit 167. The controller 110 may select a paste location by using third location information (X3 and Y3 coordinates) corresponding to touch 1012 of the input unit 167 received from the touch screen controller 195, and fourth location information (X4 and Y4 coordinates) corresponding to hovering 1012 a. The controller 110 may map device information of the input unit 167 stored in advance with third location information or fourth location information to store the mapping result in a temporary storage space or clip board in the note application 720. The controller 110 may provide at least one of visual feedback (for example, a flash, and a video) through the touch screen 190, auditory feedback (for example, output of a sound) using the speaker 163, and haptic feedback (for example, output of vibrations) using the vibration motor 164 in correspondence to selection of a paste location.

The controller 110 may perform a control to transmit a second control signal corresponding to haptic feedback (for example, output of vibrations) to be output from the pen vibrating element 544 in a Bluetooth Serial Port Profile (SPP) through a communication unit in response to device information of the input unit 167 stored in advance and selection of a paste location. The input unit 167 may output haptic feedback from the pen vibrating element 544 based on a second control signal received from the portable apparatus 100.

The controller 110 may perform a control to transmit a second control signal corresponding to haptic feedback and a second control signal corresponding to auditory feedback (for example, output of a sound) to be output from the pen speaker 543 in response to device information of the input unit 167 separately stored in advance and selection of a paste location to the input unit in a Bluetooth SPP through a communication unit. The input unit 167 may output auditory feedback (for example, output of a sound) from the pen speaker 543 based on the second control signal received from the portable terminal 100. The pen controller 510 may provide one of haptic feedback and auditory feedback, or provide a combination of haptic feedback and auditory feedback.

The controller may perform a control to transmit a second control signal where haptic, auditory, or visual feedback provided by the portable apparatus 100 is the same as haptic, auditory, or visual feedback provided by the input unit 167, and/or another control signal through a communication unit.

In step S903 of FIG. 9, it is determined whether a paste command is received via a button of the input unit 167.

Referring to FIG. 10B, the controller 110 may receive a paste command of the copied object 711 from the input unit 167 in a BluetoothSPP. The controller 110 maps the received paste command with device information of the input unit 167 stored in advance to store the mapping result in the storage. The controller may display an object (711 b in FIG. 7G) of a predetermined size at a paste location in response to the received paste command.

When the button 542 is pressed 1013 by the user, the pen controller 510 converts an operation mode of the input unit 167 into a paste mode. The pen controller 510 may perform a control to transmit a paste command to the portable apparatus 100 through the pen communication unit 520. The paste command may be transmitted periodically (for example, every 50 ms) for a predetermined time period (for example, 5 s) through the pen communication unit 520 under the control of the pen controller 510. The predetermined time period may be variably regulated. When the button 542 is pressed once more by the user, the pen controller 510 may release a paste mode, which is a current operation mode of the input unit 167. When the button 542 of an input unit 167 that is hovering is pressed 1013 by the user, the pen controller 510 may convert an operation mode of the input unit 167 into a paste mode. If an input is generated by touching the button 542, when the button 542 is of a button type, the pen controller 510 may convert an operation mode of the input unit 167 into a paste mode. The pen controller 510 may perform a control to transmit a paste command to the portable apparatus 100 in a Bluetooth SPP through the pen communication unit 520. The paste command may be transmitted periodically (for example, every 50 ms) for a predetermined time period (for example, 5 s) through the pen communication unit 520 under the control of the pen controller 510. When the button 542 is pressed once more by the user, the pen controller 510 may release the paste mode, which is a current operation mode of the input unit 167.

When it is determined that a paste command is received in step S903 of FIG. 9, visual feedback is displayed on the touch screen and a control command corresponding to haptic feedback is transmitted to the input unit, in step S904.

Referring to FIGS. 10C and 10D, the controller displays visual feedback 1014 for expanding the object 711 b of a predetermined size to an object 1011 in response to the received paste command. The visual feedback 1014 expands the object 1011 to an original size (for example, 200 pixels×240 pixels) with reference to a third touch location. The visual feedback 1014 gradually expands from the predetermined size 711 b of the object to an original size of the object 1011 at a constant rate. Further, the visual feedback 1014 expands the object with reference to a central location of the paste location.

The controller 110 may perform a control to transmit a second control signal to the input unit 167 in a Bluetooth SPP by using device information of the input unit 167 stored in advance in response to the received paste instruction. The second control signal may include haptic information on haptic feedback 1015 to be output through the pen vibrating element 544. The second control signal may include auditory information on auditory feedback 1016 to be output through the pen speaker 543. The auditory information may include a sound source output through the pen speaker 543. The input unit 167 may store auditory information corresponding to haptic information corresponding to haptic feedback, and auditory information corresponding to auditory feedback in the pen memory 550 in advance. The control information may include a file name, a file type, pen speaker activation information, sound intensity information, and pen speaker deactivation information corresponding to a sound source stored in the pen memory 550.

The controller may simultaneously perform transmission of a second control signal to the input unit 167 and displaying of visual feedback, or may perform one of transmission of a second control signal and displaying of a visual feedback first.

According to an embodiment of the present invention, additional visual feedback 1014 a using a new object 1014 b may be selectively provided. Referring to FIG. 10D, when the visual feedback 1014 is displayed, the new object 1014 b is displayed adjacent to the object 711 b. The new object 1014 b is a full pipette that has suctioned a liquid. The controller may display the pipette 1014 b, which gradually decreases in liquid content in response to the visual feedback 1014 by which the size of the object 711 b is gradually expanded to a predetermined size. When the object 1011 is completely expanded to a predetermined size, the controller 110 may display an empty pipette 1014 c, which no liquid. The controller may display the pipette 1014 c for a predetermined time period (for example, 500 ms).

The controller 110 may perform a control to output haptic feedback through the vibration motor 164 as well as through visual feedback in response to the received copy command. The controller 110 may vibrate the vibration motor 164 to correspond to haptic information as shown in FIG. 11 to provide a haptic feedback. FIG. 11 is described in greater detail below with respect in step S905 of FIG. 9. The controller 110 may perform a control to output a sound source corresponding to auditory feedback through the speaker 163 as well as visual feedback in response to the received copy command.

In step S905 of FIG. 9, the input unit provides haptic feedback and auditory feedback.

Referring to FIGS. 10C and 11, the pen controller 510 may receive a control command in a Bluetooth SPP through the pen communication unit 520. The pen controller 510 may control such that the pen vibrating element 544 outputs haptic feedback corresponding to haptic information included in control information in response to the received control command.

The transverse axis (X axis) of FIG. 11 represents a vibration time period of the vibrating element 544, in units of 50 ms 1105 a. The longitudinal axis (Y axis) represents a vibration intensity of the vibrating element 544, in units of 500 mV 1105 b. It can be seen that the haptic waveform corresponding to the haptic information of FIG. 11 rapidly increases from 0 V to 1.3 V and gradually decreases to 0V in the vibration.

In a preprocessing section 1110 a, the pen controller 510 may analyze and/or store control information received by the portable apparatus 100 and supply electric power to the pen vibrating element 544. For example, the preprocessing section 1110 a may refer to a section before vibrations are generated in the pen vibrating element 544.

An acceleration section 1110 b refers to a section in which a vibration time period and a vibration intensity of the pen vibrating element 544 increase. A maximum intensity 1110 d of the acceleration section 1110 b may be changed according to a file size and a copy processing time period included in the copy information. For example, the maximum acceleration section and the maximum intensity of the acceleration section whose file size is 1 MB may be greater than those of the acceleration section whose file size is 500 KB. The copy processing time period and the maximum intensity of the acceleration section whose copy processing time period is 1.5 s may be greater than those of the acceleration section whose copy processing time period is 500 ms.

A deceleration section 810 c refers to a section in which vibrations of the pen vibrating element 544 corresponding to the maximum intensity 1110 d decelerate. The pen controller 510 may complete outputting of haptic feedback in the deceleration section 1110 c. The time axis of the deceleration section 1110 c may be shorter than or equal to the time axis (X axis) of the acceleration section 810 b. In an embodiment of the present invention, various haptic waveforms (for example, FIGS. 13 to 15) whose vibration time periods, vibration periods, vibration intensities are different may be stored in addition to FIG. 11, and another haptic waveform may be generated and stored by using a combination of the haptic waveforms (for example, FIGS. 13 to 15) that are stored in advance.

The pen controller 510 may perform a control to output auditory feedback corresponding to auditory information (for example, a sound source) included in control information, from the pen speaker 543, in response to the received control command. The pen controller 510 may perform a control to selectively output one of haptic feedback and auditory feedback.

In step S906 of FIG. 9, it is determined whether copy information including object data exists in the memory of the input unit.

The controller 110 may identify existence of copy information including object data in the pen memory 550 of the input unit 167 by using device information and copy information of the input unit 167 stored in advance.

According to the result of the determination, the controller 110 may request copy information including object data from the input unit 167 by using device information. In an embodiment of the present invention, it will be easily understood by those skilled in the art that the identification of copy information including object data may be performed in steps S901 to S904.

When it is determined that copy information including object data exists in the pen memory of the input unit in step S906, copy information including object data is received from the input unit, in step S907.

The controller 110 may perform a control to request and receive copy information including object data from the pen communication unit 520 of the input unit 167 in a Bluetooth SPP. The copy information may include object data, a file name, a file size, a file type, a file storage location, and a copy time period. The controller 110 stores copy information including the received object data in the storage. When copy information including object data is received from the input unit 167, the controller 110 may complete outputting of visual, haptic, and auditory feedback provided from the portable apparatus 100.

In step S908 of FIG. 9, an object is displayed.

Referring to FIG. 10E, the controller 110 displays the object 1011 by using the received copy information. Two identical objects are displayed on the application screens 710 and 720 of the touch screen.

Returning to step S903 of FIG. 9, when a paste command is not received via a button of the input unit 167, it is determined whether a touch gesture of the input unit is detected, in step S909.

When a touch gesture of the input unit is not detected in step S909 of FIG. 9, the methodology terminates.

When a touch gesture (for example, a rotation, a flick, or a long press) by the input unit 167 is detected from the touch screen 190, the controller 110 may detect a continuous movement (for example, continuous X and Y coordinates corresponding to a movement of the touch gesture) (not shown) of the touch 1012 by using the touch screen 190 and the touch screen controller 195. The controller 110 may store a continuous movement starting from the detected touch 1012 in the storage. The continuous movement of the touch 1012 means that a contact on the touch screen is continued. For example, a long press may refer not to a continuous movement of a touch, but to a touch gesture whose touch maintenance time period is 2 s or more.

When a touch gesture of the input unit 167, which is hovering, is input to the touch screen 190, the controller may detect a continuous movement by using the pen recognition panel 191 and the touch screen controller. The controller may store a continuous movement starting from the detected hovering location in the storage.

It will be easily understood by those skilled in the art that a touch gesture may be changed through setting of an environment in step S909 of FIG. 9.

When a touch gesture of the input unit is detected in step S909 of FIG. 9, a copy icon is displayed, in step S910.

Referring to FIG. 10F, the controller may display a paste icon 1020 in response to an input touch gesture. It will be easily understood by those skilled in the art that the icon displayed in response to the touch gesture may be added, changed, or deleted to correspond to a performance or structure of the portable apparatus 100.

In step S911 of FIG. 9, a paste command is received via selection of the paste icon.

Referring to FIG. 10G, the paste icon 1020 is selected by the input unit 167. The controller 110 receives a paste command corresponding to the selection of the paste icon 1020 by the input unit 167. The controller 110 maps the received paste command with device information of the input unit 167 stored in advance to store the mapping result in the storage. When the paste icon 1020 is selected, the controller may perform a control not to display the icon group 720.

The controller 110 may perform a control to transmit a mode conversion signal of the input unit 167 corresponding to the input paste command to the input unit. The pen controller 510 converts an operation mode of the input unit 167 into a paste mode in response to the received mode conversion signal. When the button 542 is pressed by the user, the pen controller 510 may release a paste mode, which is an operation mode of the input unit 167.

When a paste icon 1020 is selected by the input unit 167 that is hovering, the controller 110 may perform a control to transmit a mode conversion signal of the input unit 167 corresponding to the input paste command to the input unit. The pen controller 510 converts an operation mode of the input unit 167 into a paste mode in response to the received mode conversion signal. When the button 542 is pressed by the user, the pen controller 510 may release a paste mode, which is an operation mode of the input unit 167.

When a paste command is input by selection of the paste icon in step S911 of FIG. 9, the methodology continues to step S904.

Returning to step S906 of FIG. 9, when copy information including object data does not exist in the memory of the input unit, copy information is received from an external server, in step S912.

The controller 110 may perform a control to request and receive first copy information without object data from the pen communication unit 520 of the input unit 167 in a Bluetooth SPP. The controller 110 may perform a control to request and receive a download of object data stored in an external server from the external server by using copy information stored in the storage in advance, an URL of the external server, and a communication unit.
